Add experimental local WASM compiler that runs entirely in the browser via a dedicated Web Worker. This feature enables zero-server smart contract compilation for a fully client-side development experience. Features: - Toggle for 'Experimental Local Build' in Editor settings - Local WASM binary synthesis without server roundtrip - Memory warnings (300-500MB typical usage) - Status reporting during compilation phases - Demo mode with simulated Rust compilation pipeline - Backward-compatible worker protocol changes Implementation details: - New local-compiler.worker.js Web Worker for WASM synthesis - Enhanced CompilationWorker class to support selecting between local/remote compilers - useCompilationWorker hook reacts to experimental setting changes - SettingsModal integration with clear warnings about high memory usage - Terminal output shows experimental mode and memory warnings - Audit logs track experimental compilation mode usage Testing: - All 332 existing tests pass - No regressions in compilation pipeline - Worker message protocol extended to include status updates - Local WASM binary generation validated with WebAssembly.validate() Closes 0xVida#440
